A bit of rambling on a Sunday night- useful rambling I hope. 6 years ago I obtained a job as a newhire aerospace parts engineer for a large company that had a veteran design engineer brought over from the former Janitrol firm. R-D as I shall call him, had attempted to retire at age 65 and found that retirement was not for him. A massively experienced aerospace engineer he was, loving person, and role model to me. R-D used to give me math problems to do to test my acumen, this from a retired man well past age 70. While working at the aerospace parts company I often found Janitrol drawings with R-D's signature on them as the principal engineer, going back to the early 1960s! RD was so humble that he never mentioned such things, I discovered it by chance. I owe R-D a debt of gratitude for being a model engineer, citizen, and someone who had such soul and integrity. I aspire to be his kind of engineer and pilot.
